I need a little help in PovRay. I want to create an object based on something I only know the German word for it: "Rotationsparabolid".
I guess the least of you (and probably not even most of the Germans here) know what this means so here the explanation: It's a 3-dimensional object described by two quadratic functions (eg. z = f(x,y) = x² + y² )
My problem is that I know it's possible but I don't know how. I remember reading through the documentation a couple of years ago and there was a picture with several white "half eggs" neatly aligned. And those objects are what I am looking for.
Even if you don't know what I'm talking about but know a little about PovRay. Can you help me create an object with that certain formula given?
Tahnks in advance
